This is a general review of world literature and attitudes toward propaganda campaigns aimed at regulating population growth in the USSR. The goals, strategies, and psychological methods used in such campaigns are examined, and social attitudes toward population dynamics and family planning are explored. (SUMMARY IN ENG)  相似文献

Studies were made of rapid error correction movements in eight subjects performing a visually guided tracking task involving flexion-extension movements about the elbow. Subjects were required to minimize reaction times in this two-choice task. Errors in initial movement direction occurred in about 3% of the trials. Error correction times (time from initiation to reversal of movement in incorrect direction) ranged from 30-150 ms. The first sing of correction of the error movement was a suppression of the electromyographic (EMG) activity in the muscle producing the error movement. This suppression started as early as 20-40 ms after the initiation of the error-related EMG activity and as much as 50 ms before any overt sign of limb movement. The correction of the error movement was also accompanied by an increase in the drive to the muscle which moved the arm in the correct direction. This increased activity always occurred after the initiation of the error movement. it is concluded that the first step in the error correction, suppression of drive to the muscle producing the error movement, cannot be based on information from the moving limb. It is thus suggested that this earliest response to the error movement is based on central monitoring of the commands for movement.  相似文献

The history of psychological science in the Philippines is considered as a case of cultural diffusion from the West through the English language and the institutions (educational and legal, business and industry, the media, government and the bureaucracy) which adopted the language. The development of academic and professional psychology and of psychology-related services has been phenomenal, particularly in the last decade. It has however, given rise to problems of (1) standards and validity in testing and research, and (2) applicability of concepts and methods in social psychology the roots of which are from another culture. Current trends and issues, as well the movement for indigenous Philippine social psychology, are briefly described.  相似文献

Attributions, beliefs about control, and adjustment to breast cancer   总被引:9,自引:0,他引:9  
Attributions for cancer and beliefs about control over cancer were examined for their association with adjustment to breast cancer. Although 95% of the respondents made attributions for their cancer, no particular attribution (e.g., stress, diet) was associated with better adjustment. Analyses of attributions of responsibility for the cancer to the self, environment, another person, or chance yielded only a negative relation between adjustment and blaming another person. In contrast, both the belief that one could now control one's cancer and the belief that others (e.g. the physician) could now control the cancer were significantly associated with good adjustment. Of the different types of control, cognitive control was most strongly associated with adjustment, behavior control was less strongly associated with adjustment, and information control and retrospective control were unassociated with adjustment. The theoretical and practical implications of these results are discussed.  相似文献

This paper proposes test statistics based on the likelihood ratio principle for testing equality of proportions in correlated data with additional incomplete samples. Powers of these tests are compared through Monte Carlo simulation with those of tests proposed recently by Ekbohm (based on an unbiased estimator) and Campbell (based on a Pearson-Chi-squared type statistic). Even though tests based on the maximum likelihood principle are theoretically expected to be superior to others, at least asymptotically, results from our simulations show that the gain in power could only be slight.  相似文献

Jung’s final psychoid theory of archetypes was an additional attempt to find a solution to the philosophical problem of how to relate mind and matter. In the following essay Jung’s solution is summarized by a set of 17 theses, and Jung’s philosophy will be called psychoid monism. According to psychoid monism, what ultimately and primarily is, is the psycho-physically neutral domain of instinctual experience. The origin of this view can be traced back to Post-Kantian German Idealism (Schopenhauer, Schelling, Hölderlin), and a systematization of the view requires a dialectic approach and, in particular, contradiction-tolerant dialectic logic.  相似文献

Nancy Suchman's work highlighted the fundamental role of maternal mentalization in maternal addiction, mental health, and caregiving challenges. In this study, we aimed to examine the role of mental-state language (MSL) as a measure of mentalization in prenatal and postnatal narratives and their sentiment in a sample of 91 primarily White mothers from the western United States, followed from the second trimester of pregnancy, through the third trimester, to 4 months postpartum. Specifically, we investigated the use of affective and cognitive MSL in prenatal narratives when mothers visualized caring for their baby and postnatal narratives when mothers compared their prenatal visualization to the current caregiving reality. Results indicated moderate consistency in MSL between the second and third trimesters, but prenatal and postnatal MSL was not significantly correlated. Across all time points, higher use of MSL was related to more positive sentiment, indicating an association between mentalization and positive caregiving representations across the perinatal period. Women used more affective than cognitive MSL in prenatal imagination of caregiving, but this pattern was reversed in their postpartum reflection. Implications on assessing parental mentalization prenatally and considering the relative dominance of affective and cognitive mentalizing are discussed while considering study limitations.  相似文献
